2 Wheel Drive Bike

Maybe once a year I will see a bike on the roads built to be propelled by arm power rather than leg power. Well, reader Scott built a bike that could be propelled by all four appendages. Text and picture credit goes to Scott. If readers are aware of bikes that have a non-traditional propulsion set up, feel free to contact us for posting.

Built from all dump pick parts, the double top tube frame had the right side removed for clearance of the chain during right hand turns.

Matching 26 x 1.5 coaster brake wheels, the gearing of the hand cranks was chosen for low cadence for better handling. The hand cranks were made of pedal bearings with sections of steel handle bars soldered in place to except a normal grip and still allow the bearings to be serviced at a later date.
